Integrating Design-Oriented Experiments into the Chemical Engineering Laboratory

工程-化学（53）我们之前在NSF赞助的项目下获得资助，在该项目中，我们通过使用AspenPlus模拟软件集成设计，该软件是为在四年制化学工程课程的讲座课程中使用而开发的。在这个项目中，设计的整合扩展到包括开放式的设计为导向的经验，在化学工程实验室。在这个项目中，我们的学生在一个开放式的，设计-建造-测试实验中工作，在填充柱设计的气体吸收。这个实验现在是我们大四化学工程实验室必修课的一部分。它是仿照一个典型的工业项目，学生必须在竞争的替代方案之间做出设计选择，其中必须考虑经济性。学生们正在使用AspenPlus模拟吸收过程，并在替代柱和柱填料配置之间做出选择。我们的学生正在实验室中构建和测试他们的设计，并以书面或口头报告的形式报告他们的发现。我们正在通过学生访谈、对高年级学生和毕业生、雇主以及该项目的工业咨询委员会的调查来评估该项目的有效性。

Engineering - Chemical (53)We were previously funded under an NSF-sponsored project, in that program we integrated design through the use of AspenPlus simulation software which was developed for use in lecture courses throughout the four-year chemical engineering curriculum. In this project, the integration of design is expanded to include open-ended design-oriented experiences in the chemical engineering laboratory. Under this project we have our students working in an open-ended, design-build-test experiment in packed column design for gas absorption. The experiment is now part of our required senior-year chemical engineering laboratory course. It is modeled after a typical industrial project in which students are required to make design choices between competing alternatives where economics must be considered. Students are using AspenPlus to model the absorption process and make choices between alternative columns and column packing configurations. Our students are building and testing their design in the laboratory and report their findings in a written or oral presentation. We are assessing the effectiveness of this project by using student interviews, surveys of senior students and graduates, employers as well as the program's industrial advisory board.
